Answer:
25 meters
Step-by-step explanation:
Since it is a rectangle, the formula of the perimeter will be 2w+2l.
35(2)+2(x)=120.
2x=50
x=25
646 is 190% of 340
Simply do the following,
1) divide,
![646 \div 340 = 1.9](https://tex.z-dn.net/?f=646%20%5Cdiv%20340%20%3D%201.9)
2) multiply the above answer by 100
![1.9 \times 100 = 190](https://tex.z-dn.net/?f=1.9%20%5Ctimes%20100%20%3D%20190)
3) dock on that percent sign,
![190\%](https://tex.z-dn.net/?f=190%5C%25)
